Description

Technical Field

[0001] This utility model relates to the field of mortar preparation technology, specifically to a mixing device for preparing plastering mortar. Background Technology

[0002] Mortar applied to the surface of buildings or building components is collectively referred to as finishing mortar. Based on their function, finishing mortar can be divided into ordinary finishing mortar, decorative mortar, and finishing mortar with certain special functions (such as waterproof mortar, heat-insulating mortar, sound-absorbing mortar, and thermal insulation mortar). Finishing mortar requires good workability, easily applied as a uniform and smooth thin layer for convenient construction. It should also have high adhesion, ensuring the mortar layer bonds firmly to the substrate without cracking or peeling over a long period.

[0003] Most existing mortar preparation mixing mechanisms require manual feeding of raw materials into the mixing drum. Some mixing drums are too tall, making it inconvenient to add raw materials, which is not conducive to automated production. Furthermore, during mixing, raw materials are very easy to stick to the inner wall of the mixing drum, resulting in low output rate, waste of a large amount of raw materials, and increased production costs.

[0029] In use, the raw materials are poured into the feeding box 7, and the lifting motor 401 is started, driving the first rotating shaft 402 to rotate. This causes the first rotating gear 403 to drive the driven gear 404 to rotate, and the driven gear 404 to drive the threaded rod 405 to rotate. This causes the lifting plate 406 to move upward, guided by the guide post, until the upper surface of the lifting plate 406 contacts the bottom surface of the limit ring 408.

The front of the feeding plate 604 slides along the leak-proof shell 102 to prevent the raw materials from spilling from the front and back during rotation. When the feeding plate 604 is perpendicular to the fixed plate 5, the electric push rod 607 is turned off. At this time, the raw materials in the feeding box 7, under the cooperation of the trapezoidal block 702 and the inclined block 9, enter the mixing drum 2 from the feeding box 7, completing the mixing process. For the feeding of raw materials, the mixing device of the mixing drum 2 can facilitate the feeding of raw materials, greatly improving the work efficiency. Connect the water inlet 12 to the water pipe to send water into the mixing drum 2. Start the mixing motor 111 to drive the mixing rod 112. The raw materials are fully mixed by the long mixing blade 113 and the short mixing blade 114. During the mixing process, start the rotating motor 141 to drive the second rotating shaft 142 to rotate, which in turn causes the second rotating gear 143 to drive the gear ring 144 to rotate. The gear ring 144 rotates around the sleeve 149 through the connecting rod 148 and the rotating ring 150, thereby driving the scraper 146 to scrape off the raw materials adhering to the inner wall of the mixing drum 2, preventing excessive accumulation and waste of raw materials. Open the solenoid valve 17 to allow the mortar formed after mixing to pass through the feeding hopper 15 and flow out from the discharge port 16, completing the preparation of the plastering mortar.
